Zusammenfassung:The invention comprises the materialization of an original object (1) with an increased security level based on the processing of an original image (3) and of a digital marker with encoded information relating to the original image (5). The invention comprises a method for validating an object to be validated (2) having an image to be validated (4) and a digital marker to be validated (6), which compares encoded Information calculated from at least one image to be validated (4) with encoded information corresponding to at least one original image (3), by means of the processing of the encoded information present in at least one digital marker to be validated (6). The invention comprises computer equipment, computer programs and appropriate means for reading on a computer device. The invention aims to create mechanisms and instruments for controlling the authenticity of objects in the technical field of security printing. L'invention porte sur la matérialisation d'un objet original (1) à niveau de sécurité intensifié sur la base du traitement d'une image originale (3) et d'un marqueur numérique avec information codée de l'image originale (5). L'invention concerne un procédé de validation d'un objet à valider (2) possédant une image à valider (4) et un marqueur numérique à valider (6), qui compare les informations codées calculées à partir d'au moins une image à valider (4) avec des informations codées correspondant à au moins une image originale (3), au moyen du traitement des informations codées présentes dans au moins un marqueur numérique à valider (6). L'invention concerne des appareils informatiques, des programmes d'ordinateur et des moyens de lecture par appareil informatique adaptés. L'invention vise à obtenir des mécanismes et des instruments de contrôle d'authenticité d'objets dans le domaine technique de la graphique de sécurité. A invenção compreende a materialização de um objeto original (1) com nível de segurança intensificado com base no processamento de uma imagem original (3) e de um marcador digital com informação codificada da imagem original (5). A invenção compreende um método para validação de um objeto a validar (2) possuindo uma imagem a validar (4) e um marcador digital a validar (6), que compara informações codificadas calculadas a partir de pelo menos uma imagem a validar (4) com informações codificadas correspondentes a pelo menos uma imagem original (3), por meio do processamento das informações codificadas presentes em pelo men
